DETAILED DESCRIPTION

In the following description, numerous specific details are set forth inorder to provide a thorough understanding of the present embodiments. Itwill be apparent to one having ordinary skill in the art, that thespecific detail need not be employed to practice the presentembodiments. In other instances, well-known materials or methods havenot been described in detail in order to avoid obscuring the presentembodiments.

FIG. 1 shows an embodiment of a surgical inflation and delivery system1000 (hereinafter “System 1000”). FIG. 1 shows a container 10 comprisinga compartment, delivery tube, or lumen with an inner surface 11 andouter surface 12 extending from a first end 20 to a second end 30. Thefirst end 20 has a diameter 17 a, and the second end has a diameter 17b. First end 20 is configured to receive a hollow shaft 55. The hollowshaft 55 is configured to receive fluid at an inlet 55 a and to delivera fluid at an outlet 55 b. Outlet 55 b is positioned between the firstand second end of the container and is in fluid communication with aninlet 101 of contents 100, which are also positioned between the firstend 20 and second end 30. Thus, when inlet 55 a receives a fluid via asyringe, saline bag or other fluid source, the fluid travels through thehollow shaft 55, is delivered out of outlet 55 b and into inlet 101 toinflate contents 100.

Additionally, FIG. 1 shows a hook, clamp or clip (hereinafter “clip 59”)coupled to shaft 55 and located proximal to the first end 20. Clip 59may have a first point of attachment 59 a to the shaft (hereinafter“point 59 a”) and a second point of attachment 59 b (hereinafter “point59 b”), wherein point 59 b is positioned between the first point 59 aand the first end 20 of container 10. Clip 59 may be configured topartially or completely encase shaft 55. Responsive to clip 59 partiallyor completely encasing shaft 55, point 59 b may be positioned adjacentto first end 20. The diameter 17 d of clip 59 exceeds the diameter 17 aof first end 20. Thus, clip 59 s, reduces, or prevents the hollow shaft55 from sliding, moving, or translating beyond point 59 b into the firstend 20 of the container 10. In other words, when clip 59 is coupled tothe shaft 55, the portion of the shaft 55 between point 59 b and theproximal end of shaft 55 remains outside or proximal to container 10.Or, when inlet 55 a is at the proximal tip of shaft 55, the distancebetween point 59 b and the proximal end of shaft 55 remains outside orproximal to container 10. Other configurations designed to preventrelease of outlet 55 b are described below and include but are notlimited to use of a bag, protrusions, an inner rail, or disc.

Alternatively, the second end 30 may designed with a diameter less thanthe diameter of the first end and the outlet 55 b, but having a diameterequal to or greater than the diameter of inlet 101. A narrowed secondend 30 diameter has the additional benefit of limiting, reducing, orpreventing the outlet 55 b from exiting the second end, as illustratedin FIG. 12A.

Additionally, FIG. 1 shows multiple raised surfaces in system 1000.Surface 11 s is positioned between the first end 20 and second end 30.Surface 11 s may include one or more protrusion(s), bump(s), dot(s),abutment(s), shelve(s), ledge(s), ridge(s) or tab(s) (hereinafter“container protrusion 11 p”) on the inner surface 11 of the container.In FIG. 1, container protrusion 11 p has a circular shape forillustrative purposes. Surface 101 s is positioned on the outer surfaceof inlet 101, and surface 101 s may include one or more protrusion(s),bump(s), dot(s), abutment(s), shelve(s), ledge(s), ridge(s) or tab(s)(hereinafter “content inlet protrusion 101 p”) on the outer surface ofinlet 101. In FIG. 1, content inlet protrusion 101 p has a triangularshape for illustrative purposes. Surface 55 s is positioned on the outersurface of outlet 55 b and may include one or more protrusion(s),bump(s), dot(s), abutment(s), shelve(s), ledge(s), ridge(s) or tab(s)(hereinafter “outlet protrusion 55 p”). In FIG. 1, outlet protrusion 55p has a rectangular shape. It will be appreciated that the shapes and/orsizes of the elements shown in system 1000 may vary, such as containerprotrusion(s) 11 p, content inlet protrusion(s) 101 p, and outletprotrusion(s) 55 p. The shapes illustrated are for illustrative purposesand may be interchanged or substituted with alternative shapes, as shownin FIGS. 7A-7D and further described below.

FIG. 1 also shows an embodiment of content 100, wherein the contentincludes a balloon 105 connected by a lumen or hollow elongated member104, to another balloon, with an inlet for inflation (hereinafter“content inlet 101”). The elongated member 104, balloons 105, and inlet101 form a “Y shape” with the inlet 101 at the base portion of the “Y.”In other embodiments the lumen and balloons may form a “V” or “U” shape.In embodiments including more than two balloons, the elongated membermay form more complex shapes, such as for example a “W”.

Embodiments of Content 100 may include a plurality of balloons 105 and aplurality of inlets 101. Other embodiments may include a single balloon105 and a single inlet 101, which may or may not be connected by ahollow lumen or elongated member 104. In other words, content 100 mayinclude one or more balloons, or one or more balloon components.

Balloons 105 may be seamed balloons, or welded with heat. They may,among other embodiments, be pleated, pillowed, a paddle shaped, foldableor ultra-thin. In a surgical setting, the balloons may be configured tohold 0-100 ml, 100 ml-200 ml, 200 ml-300 ml, 300 ml-400 ml, 400-500 ml,500-600 ml, or more than 600 ml for particularly large patients. Theballoon(s) may have varying odometers and burst pressures and beconfigured for a heat-shrunk tubing or other commercially availabletubing. For example, in a minimally invasive context the compliancerange may be 0-15%, the balloons may transmit light over a broadspectrum including ND, the sizes may range from 0.5 to 50 mm, and theburst pressures may range from 5 to 500 PSI.

In other embodiments, content 100 may include any device configured tobe inflated, such as catheter, of inflatable devices such as the organretractor described in U.S. Pat. App. Publication No. 2012/13/432,960,which is incorporated by reference.

FIGS. 2A-2D show inflation and delivery of content 100 in an embodimentwhere content 100 requires inflation outside of the container 10. FIG.2A shows a first configuration of system 1000 wherein content 100 is ina first position, wherein the first position may occur before deliveryof content 100. FIG. 2B shows a second configuration where content 100is partially or completely distal to the second end 30 and ready forinflation. FIG. 2C shows release of content inlet 101 and content 100from outlet 55 b. FIG. 2D shows release of content 100 from the system1000.

FIG. 2A shows a first configuration, wherein system 1000 includescontent 100 disposed within container 10 between the first end 20 andsecond end 30. Content 100 is affixed to a content inlet 101, which inturn is coupled to outlet 55 b and hollow shaft 55. Shaft inlet 55 a isproximal to the first end 20. The proximal portion of hollow shaft 55 iscoupled to a detachable clip 59, which limits, reduces, and/or preventsthe shaft inlet 55 a from sliding into the first end of container 10. Inembodiments, when inflation of content 100 would result in an expandedcontent diameter 17 c being less than the container diameter 17 b, fluidmay be delivered into inlet 55 a, and the contents may be inflated inthe first position, prior to release. However, in embodiments wheninflation of content 100 would result in an expanded content diameter 17c being greater than or equal to diameter 17 b, fluid may be deliveredafter the content 100 is delivered outside of or distal to second end 30of container 10.

FIG. 2B shows a second configuration wherein hollow shaft 55 has beenpressed into a second position and the content 100 has been deliveredoutside of or distal to the second end 30 of container 10. In the secondposition, clip 59 limits, reduces, or prevents movement of translationof the hollow shaft 55 beyond point 59 b into the first end 20 ofcontainer 10. Specifically, point 59 b is proximal to or in contact withthe first end 20 of container 10. Although a portion of content inlet101 may be delivered outside of or distal to the second end 30 ofcontainer 10, content inlet protrusion 101 p remains within container10, or proximal to second end 30 of container. Specifically, contentinlet protrusion 101 p may interface with container protrusion 11 p,such that content inlet protrusion 101 p and container protrusion 11 pare positioned adjacent to each other or in contact with each other. Inembodiments, responsive to content inlet protrusion 101 p interfacingwith container protrusion 11 p, other content inlet protrusions 101 pmay be interfaced with corresponding container protrusions 11 p. Whencontent inlet protrusion(s) 101 p and container protrusion(s) 11 p areinterfaced, a rotation of outlet 55 b (for example, via rotation of theconnecting shaft 55) would cause the container protrusion(s) 11 p tohit, collide, abut, or contact content inlet protrusion(s) 101 p, suchthat rotation of inlet 101 is limited, prohibited, or eliminated. Inembodiments, content inlet protrusions 101 p and container protrusions11 p may be positioned at offsetting even or uneven intervals, such thatcontent inlet protrusions 101 p may slide or be placed between twocontainer protrusions 11 p.

Clip 59 may be positioned so that when outlet 55 b is assembled orcoupled to content inlet 101, the distance between point 59 b and thedistal end of outlet 55 b enables content inlet protrusion(s) 101 p toalign, slide into, or be adjacent to container protrusion(s) 11 p. Inother words, clip 59's placement limits, reduces, or prevents the shaft55 and attached outlet 55 b and inlet 101 from moving beyond the secondend 30, and may be configured to ensure the alignment of content inletprotrusion 101 p and container protrusion 11 p. If the clip isuncoupled, the shaft 55 and any attached components, such as outlet 55b, may fall out of the delivery system and, in a surgical setting, intothe patient.

In the configuration illustrated in FIG. 2B, content 100, which isdistal to the second end 30, may be inflated. A screw portion 101 b ofcontent inlet 101 may screw into outlet 55 b, thereby limiting,inhibiting, or preventing content 100 from releasing during inflation.This is particularly important if content 100 requires significantinflation of fluid, such as water or saline.

After inflation, outlet 55 b may be uncoupled from inlet 101 to releaseinflated content 100. FIG. 2B shows an embodiment wherein content inlet101 is coupled to outlet 55 b via a screw portion 101 b. Thus,uncoupling may be achieved by rotating clip 59 (or alternatively inlet55 a or hollow shaft 55) to rotate or unscrew outlet 55 b from contentinlet 101. As outlet 55 b rotates, one or more content inlet protrusion101 p and one or more container protrusion 11 p interface, contact,collide or lock into one another, limiting, inhibiting, or preventingrotation of inlet 101. In other words, inlet 101 is fixed or locked intoposition by the interlocking of content inlet protrusion(s) 101 p tocontainer protrusion(s) 11 p. In particular, one or more protrusions 101p collide with one or more protrusions 11 p, lock into a fixed positionand thereby limit, reduce, or prevent 101 from rotating with outlet 55b. The locked position of inlet 101, facilitated by content inletprotrusion 101 p and container protrusion 11 p, enables a practitionerto unscrew outlet 55 b from content inlet 101 when, for example, the twocomponents are configured as complementary male and female lure screwportions.

The raised surfaces and/or protrusions may be configured to limit,prevent, or reduce rotation along the horizontal axis, but allowmovement along the vertical axis (wherein the vertical axis extends fromthe first end 20 to the second end 30, and the horizontal axis isperpendicular to the vertical axis). Thus, in the embodiment above,vertical movement of translation of inlet 101 is not limited, reduced,or prevented by the container protrusion 11 p and content inletprotrusion 101 p, but is instead limited, or reduced, prevented by clip59.

FIG. 2C shows a third configuration, wherein the outlet 55 b of system1000 is uncoupled from the inlet 101 of content 100. In thisconfiguration, gravity may exert a sufficient force to pull and releaseinlet 101 from the second end 30. Alternatively, the gravitational forcemay not be large enough, or container protrusion 11 p and content inletprotrusion 101 p may limit a gravitation release. In either scenario, apractitioner may pull the hollow shaft from the second end toward thefirst end, remove clip 59 (if attached) and push the hollow shaft towardthe second end 30 with sufficient force so outlet 55 b bumps, hits,collides, knocks against inlet 101. The application of force of outlet55 b against inlet 101 pushes the inlet 101 through and out the secondend 30 of the container 10 to facilitate a release of contents 100 fromthe system 1000. When outlet 55 b and inlet 101 are configured forcoupling via a screwing mechanism, outlet 55 b does not reattach toinlet 101 upon impact because coupling requires screwing inlet 101 ainto outlet 55 b

FIG. 2D shows a fourth configuration wherein contents 100 and inlet 101are released and separated from the delivery system 1000 and the outlet55 b is located at the second end.

FIGS. 3A-3D show embodiments configured to limit, reduce, or preventrelease of outlet 55 b from the system 1000. In this embodiment, outlet55 b may include one or more outlet protrusion(s) 55 p located on itsouter surface 55 s and along the same vertical axis as containerprotrusion 11 p. In this embodiment, when outlet 55 b moves from thefirst end 20 towards the second end 30, outlet protrusion 55 bumps,collides, contacts or locks into a container protrusion located on theinner surface 11 s at point 59 c. In particular, container protrusion 11p may bump, collide, contact or lock into one or more outletprotrusion(s) 55 p to limit, reduce, or prevent vertical translation ormovement of outlet 55 b beyond the point of contact at point 59 c.

Outlet surface 55 s may include one or more protrusion(s) 55 p locatedat the distal portion of outlet 55 b, as shown in FIGS. 3A & 3B, butthis limits, reduces, prevents the outlet 55 b from pushing or knockingout inlet 101 in the third configuration described above. Alternatively,outlet surface 55 s may include one or more container protrusion(s) 55 plocated at a middle or proximal portion of outlet 55 b, as shown inFIGS. 3C & 3D. In this configuration, sufficient vertical translation isenabled to knock out or displace outlet 101 from the system 1000.

FIGS. 3A-3D also shows embodiments wherein one or more outletprotrusion(s) 55 p may substitute use of clip 59 altogether. However,when one or more outlet protrusion(s) 55 p are located at the distalportion of outlet 55 b, as shown in FIG. 3B, a practitioner is limitedor prevented from employing outlet 55 b from pushing or knocking outinlet 101 from the second end 30, as described above. Alternatively,when one or more outlet protrusion(s) 55 p are located at a middle orproximal portion of outlet 55 b, as shown in FIG. 3D, a practitioner mayblindly adjust the vertical translation or movement of hollow shaft 55to achieve the desired horizontal alignment of one or more outletprotrusion(s) 55 p and content inlet protrusion(s) 101 p in preparationfor unscrewing outlet 55 b from inlet 101 a. Thus, use of a clip 59 tolimit vertical translation of the outlet 55 b may be the preferredembodiment.

FIGS. 3B & 3C also shows that a hollow shaft 55 may be configured with ahandle 50, wherein handle 50 may be configured to facilitate applicationof pressure upon the hollow shaft 55. The handle 50 may be positionedoutside of the body of container 10 allowing a practitioner to grip,hold, and/or interface with handle 50. Handle 50 may be configured toreceive a person's hand such that the person may apply pressure tohandle 50 to displace outlet 55 b or content 100 along the inner lumenof container 10, for example away from the first end 20 and towards thesecond end 30. Additionally, shaft inlet 55 a may be configured at theproximal portion of the handle to facilitate injection of fluid. In anembodiment, first inlet 55 a may receive fluid, which travels throughshaft 55, outlet 55 b and into inlet 101 for inflation of content 100.

FIGS. 3B and 3C also show that a second handle 60 may be located uponthe outer surface 12 of container 10 to facilitate positioning andstabilization of the container 10. This is particularly useful whenapplying force upon the shaft 55; a practitioner may grip second handle60 with one hand and apply force upon hollow shaft 55 with the otherhand.

Configurations described in FIGS. 4A through 4D also show positioning ofsystem 1000 in a minimally invasive surgery. For example, the firstconfiguration (FIG. 2A) may be a starting position before the system1000 is inserted into the patient via an incision, aperture, or asurgical port 80. After inserted into a port 80 (FIG. 2B), the distalend 30 is within the patient's interior 45 while the proximal end 20remains on the patient exterior 46 allowing for inflation of content100. Outlet 55 b may be uncoupled from content inlet 101 (FIG. 2C),while portions of container 10 may be positioned within patient'sinterior 45 while portions of container 10 may be positioned outside ofpatient's interior 45. Container 10 may slide into and outside of theport to achieve any desired configuration. After release of content 100in the fourth configuration (FIG. 2D), System 1000 may be removed fromport 80, while content 100 may remain within patient's interior 45.

FIG. 4A-4D show that a System 1000 may also include one or moreprojections or protrusions (referred to hereinafter collectively andindividually as “projection 12 a”). Projection 12 a may extend at anangle or orthogonally from outer surface 12 of container 10 and may haveany shaped perimeter, including a circular, oval trapezoidal, polygonalor any mixed shape perimeter. Projection 12 a may be slidable or slidealong the outer surface 12 or may be integral to outer surface 12.Projection 12 a may include an inner circumference that is configured tobe positioned adjacent to outer surface 12 of container 10, and theunder surface 12 c of projection 12 a may be configured to be positionedadjacent to a patient's body 45 or surgical port. Projection 12 a may beconfigured to interface with an incision or port 80 to limit themovement, slippage or sliding of container 10. If projection 12 a isinterfaced with the port or patient, the portion of container 10proximal to projection 12 a may be prevented from sliding into theinterior of a patient.

FIG. 5 shows an embodiment wherein shaft 55 is detachable from outlet 55b. Hollow shaft 55 is substituted by an inlet 55 c configured forreceiving fluid from an external source. Outlet 55 b is coupled to aninlet 55 c, located between outlet 55 b and the first end 20, orproximal to the first end 20, as shown in FIG. 4. Inlet 55 c is in fluidcommunication with outlet 55 b, and may be configured to form part ofthe outlet 55 b as a single unit, such as for example a dual female andmale luer lock. Alternatively, inlet 55 c and outlet 55 b may beseparate components coupled together.

Shaft 55 may instead be configured with a first end 55 a and a secondend 55 y, and second end 55 y may be configured to couple to inlet 55 c.In this configuration, fluid is received at inlet 55 a, travels throughthe hollow shaft 55, leaves outlet 55 y and travels into inlet 55 c.

In another embodiment, a hollow shaft 55 need not be employed. Instead,a stick or shaft 56 (which may or may not be hollow) may be employed toapply pressure to the inlet 55 c to translate the outlet 55 b throughcontainer, for example from the first end 20 to the second end 30.Alternatively, inlet 55 c or outlet 55 b may be comprised of an outersurface 55 d facing or open to the first end 20. A stick or shaft 56(which may or may not be hollow) may be employed to apply pressure uponouter surface 55 to translate the outlet 55 b, content inlet 101 andcoupled content 100 toward the second end. In either embodiment, fluidmay be inserted in inlet 55 c via other means, such as a syringe IV orconnecting tube once the desired displacement is achieved.

FIGS. 6A-6C shows an embodiment wherein content inlet 101 remainsattached to an inner lumen 51 after delivery and deployment. Lumen 51may include an inlet 51 a positioned on a first end of lumen 51, anoutlet 51 b positioned on a second end of lumen 51, and a diametersmaller than the diameter of outlet 55 b. Outlet 51 b is configured forattachment or coupling to content inlet 101 or content 100. Inlet 51 aof lumen 51 may have various configurations. In one embodiment, aportion of the inner lumen may couple to or be integral to hollow shaft55, wherein the inlet 51 a may be the same component as inlet 55 a.Alternatively, as shown in FIG. 6A, the inner lumen 51 may pass betweenthe walls of the shaft and share an inlet 55 a with shaft 55. As shownin FIG. 6B, inner lumen 51 may extend beyond or proximal to shaft inlet55 a and have a separate inlet 51 a. Alternatively, the lumen may notpass through shaft 55, but pass between the inner surface 11 ofcontainer 10, adjacent to the outlet 55 b, or through a separate outletlocated on outlet 55 b. Alternatively, lumen 51 may pass outside thesurface of container 10 (as shown in FIG. 6C). In any of theabove-described configurations, lumen 51 affixes to inlet 101 via outletend 51 b and enables delivery of fluid via inlet 51 a.

An extended lumen 51 enables a practitioner to retain a lumen connectionto the contents 100 for manipulation, additional inflation, or retrievalduring surgery. A medical practitioner may seek to inject or inflateadditional fluid into content 100, which content is within the patient.

FIGS. 7A-7D illustrate various configurations of protrusion(s) 11 p andprotrusion(s) 101 p with respect to their respective surfaces 11 s and101 s and with respect to each other, from a top-down perspective. FIGS.7A-7D may also illustrate various configuration of protrusion(s) 55 pand protrusion(s) 11 p with respect to their respective surfaces 55 sand 101 s and with respect to each other (wherein the 101 components maysimply be substituted for 55 components). However, if protrusion(s) 55 pare intended to prevent the release of outlet 55 b (as described above),at least one protrusion 55 p must overlap at least one protrusion 11 pfrom a top-down perspective.

Protrusion(s) 11 p, protrusion(s) 101 p, and protrusions 55(p) may beevenly spaced (e.g., FIG. 7A) or unevenly spaced (e.g., FIG. 7B). Theymay be polygonal, curved, square, trapezoidal, mixed shape or any shape,which facilitates a locking, interfacing, or coupling function.Protrusion(s) 11 p, 101 p and 55 p may share the same shape (e.g., FIG.7C), differ in shape (e.g., FIG. 7B), or have a mixed configuration ofshapes within their respective sets (e.g., FIG. 7D). For example,protrusions 11 p may consist of a single oval shapes protrusion, asingle triangle shaped protrusion, and a polygonal shaped protrusion(all unevenly spaced) whereas protrusions 101 may consist of a series ofevenly shaped circular protrusions, or vice-versa. The protrusions maybe smooth, jagged or mixed. They may be continuous or discontinuousalong the same horizontal axis, dispersed in multiple rows, or dispersedgenerally, with a pattern or without a pattern. Protrusion(s) 11 p, 101p or 55 p may be angled with respect to their surfaces 11 s, 101 s and55 s, respectively. Protrusion(s) 11 p, 101 p and 55 p may includeadditional protrusions at an angle or orthogonal to the protrusion tofacilitate a locking function. The protrusions may have varyingthickness, different thicknesses or the same thickness. Additionally,surfaces 11 s, 101 s and 55 s need not all include protrusions. Forexample, surfaces lis and 101 s may include protrusions but surface 55 smay not include protrusions. Alternatively, surfaces 11 s and 55 s mayinclude protrusions but surface 101 s may not include protrusions.

FIGS. 8A-8E shown an embodiment of outlet 55 b and inlet 101. Otherembodiments need not include all features, such as a base portion orthreads. A luer-slip or slip tip; duck-bill or tuohy borst valve; orother commercially available valve, or luer component may equally servethe function of transmitting fluid to an inlet. U.S. Pat. No. 8,545,479;PCT/US2002/025393; U.S. Ser. No. 11/418,838; EP/2007/0120460; U.S. Ser.No. 07/627,889 or PCT/US2005/043338, for example, illustrate other valvetechnologies that may serve as a male luer component, female luercomponent, or both.

Inlets, such as inlet 55 a or inlet 101 a, may be comprised of a simplefluid inlet; valve; female luer lock, as the embodiment illustrated inFIGS. 8A-8E; luer-slip or slip tip; duck-bill or tuohy borst valve; orother commercially available valve or luer component designed to receivefluid from a saline bag, syringe, fluid delivery system, or other toolsin the operating room. Outlets, such as outlet 55 b or outlet 55 y, maybe comprised of a simple fluid outlet; valve; male luer lock, as theembodiment illustrated in FIGS. 8A-8E; luer-slip or slip tip; duck-billor tuohy borst valve; or other commercially available valve or luercomponent designed to deliver and/or receive fluid from a saline bag,syringe, fluid delivery system or other tools in the operating room.

Various inlets and outlets may be configured as one piece or as separatepieces coupled together. For example, as shown in FIG. 1, inlet 55 a,shaft 55 and outlet 55 b may be coupled or manufactured as one. As shownin FIG. 4, inlet 55 a and shaft 55 may be coupled together but separatefrom outlet 55 b, which may contain a separate inlet 55 c.

A chain of inlets and outlets may be added as desired. For example, thedistance between the System 1000's first proximal inlet (inlet 55 ashown in FIG. 1) and the inlet 101 a of contents 100 may beintermediated by multiple inlets and outlets, or male and female luerlocks. FIG. 4 shows a configuration wherein the hollow shaft 55 andoutlet 55 b are separable pieces, so that shaft 55 includes anadditional outlet 55 y configured for coupling to an additional inlet 55c of the outlet 55 b. In another embodiment, the hollow shaft 55comprises largely of a chain of inlets and outlets.

Outlet 55 b may be configured to receive a downward pressing force fromfirst end 20 towards second end 30 to facilitate movement of outlet 55 bfrom a first position adjacent to first end 20 to a second positionadjacent to second end 30. To facilitate transfer of pressure, outlet 55b, or its component sidewall or proximal surface, may include a cap,piston, plate, crown or disk portion 55 d, as shown in FIG. 1. The diskportion 55 d may be configured to receive pressure via the shaft 55, asshown in FIG. 1. Alternatively, the disk portion may be configured toreceive pressure via a separate stick, shaft or finger.

In embodiments, container 10 may be configured to store content 100 orother materials, such as bag or sheath within the tube. Content 100 maybe preassembled within container 10 or inserted into the container 10via the first proximal end 20 or second distal end 30. Content 100 maybe placed within container 10 in close proximity to first proximal end20 as shown in FIG. 4 or may be placed at a middle portion of seconddistal end 30, as shown in FIG. 1. Content 100 may be pushed out of thecontainer 10 via a pressing force upon outlet surface 55 c and mechanismdescribed below, or pulled within the body of container 10 to exitthrough second distal end 30 of container 10 pre- or post-partial orcomplete inflation. Alternatively, as content 100 receives air, fluid,and/or other substances, content 100 may move, automatically fall, or beforced out of container 10 due to increase weight, gravitational force,or force applied by being inflated and/or injected.

Container 10 may be various shapes and/or sizes, wherein a length and/orwall thickness of container 10 may be pre-specified, include one or moreinner cannula of varying thickness or length. The diameter of the firstend 17 a may be equal or different from the diameter of second end 17 b.Additionally, container 10, first end 20, second end 30, shaft 55,various inlets and outlets, protrusions, and other components andelements of system 1000 may have a perimeter of alternative shapes, suchas a circular, oval, rectangular, polygonal, or a trapezoidal perimeter.A perimeter of the inlets or outlets may have substantially the sameshape as inner surface 11 of container 10, such that the inlets oroutlets are positioned adjacent to the inner surface 11 of container 10with a diameter less than the diameter of container 10.

To facilitate movement of the outlet portion within the body ofcontainer 10, inner surface 11 of container 10 may include guide(s),track(s), or rail(s) 19. Track 19 may be configured to interface withoutlet 55 b, and outlet 55 b may also include balls or rollers 18configured to interface with the track 19, in addition to stops toprevent passage of outlet 55 b outside of the second end 30 of container10.

In another embodiment, a track, rail or guide may be located on shaft55. FIG. 12 shows an embodiment where the shaft has a rail 19. In anembodiment, container 10 may also include a disk 300 perpendicular tothe vertical axis of the container. The disk 300 may comprised of aninner hole 301, with one large hole 301 c configured for passing theshaft and two unequal sized holes, 301 a and 301 b in fluidcommunication with the large hole. Additionally, the shaft may include atab 19 t, such that 19 t is capable of sliding through hole 301 a but istoo large to slide through hole 301 b. In a first configuration, tab 19t is configured over placement over hole 301 a. Thus, when shaft 55 ispressed down, the shaft stops when tab 91 intersects hole 301 a.Conveniently, this intersection point may be positioned where protrusion11(p) and 101(p) align. In order to move the shaft further, apractitioner would rotate the device until tip 19 t intersected hole 301b. This rotation may uncouple or unscrew inlet 101 from outlet 55 b.Uncoupling may be further facilitated by one or more protrusion(s) 11 pon the inner surface 11 s, as shown in FIG. 12A, and one or moreprotrusion(s) 101 p on the inlet's outer surface 101 s. Additionally,release content 101 may further be facilitated by a narrowed second end,wherein the diameter of the second end, 17 b, is less than the diameterof the first end, less than the diameter of outlet 55 b, but equal to orlarger than the diameter of the inlet 101 so the inlet may be released.A narrow second end 30 has the additional benefit of limiting, reducing,or preventing the outlet 55 b from exiting the second end.Alternatively, the second end 30 may have an expandable diameter.

FIGS. 12B & 12C show top-down perspective of alternative embodiments ofa disk. In FIG. 12A, holes 301 a and 301 b are symmetrically placedrequired a 180 degree rotation of the shaft in order for tab 19 a toreach one hole or the other. In FIG. 12B, holes 301 a and 301 b are notsymmetrically placed. Holes 301 a and 301 b may be positioned to requireany degree of rotation.

In some embodiments, first end 20 of container 10 and second end 30 ofcontainer 10 may be configured to be open. In other embodiments, firstend 20 of container 10 may be configured to be closed or covered with ahole allowing for passage of one or more shaft, conduits, cords orlumens.

FIG. 13 shows a second end 30 of container 10 configured to include aflexible seal 15 comprised of a partial seal, mouth, teeth or prongs(referred to individually and collectively hereinafter as “flexible seal15”) wherein when pressure is applied to flexible seal 15, portions offlexible seal 15 may project outward to open flexible seal 15 allowingcontent 100 to leave container 10.

In an embodiment, the inflatable content may be housed within thecontainer and be adjacent to the second end which contains the teeth orprongs of a flexible seal. In another embodiment, the flexible seal mayextend distally from the second end of the container so the inflatablecontent is housed distal to the second end (i.e. not between the firstend and second end of the container). In another embodiment, pushingdown the fluid outlet from the first end to the second end may not berequired; instead, the inflatable content need only be inflated andreleased from the teeth, which opens as the content is inflated.

Flexible seal 15 may be positioned to cover second end 30, and may beconfigured as a delivery outlet to allow content to exit the body ofcontainer 10. Alternatively, flexible seal 15 may be positioned to coverboth the first end 20 and second end 30. Hollow shaft 55 may be rigid orflexible body. A rigid shaft may facilitate dual-use of the shaft as aninlet for fluid and as a means of applying downward force upon outlet 55b to facilitate movement and delivery of content 100 out of the secondend 30. A flexible shaft may permit injection of fluid but also requiresapplication of force upon outlet 55 b by other means, such as by anothershaft, stick or finger.

As shown in FIG. 1, hollow shaft 55 may be affixed to outlet 55 b.Alternatively, as shown in FIG. 4, hollow shaft 55 may be detachable. Asshown in FIG. 5, a hollow shaft 55 may also include one or more hollowinner tubes or lumen 51.

Hollow shaft 55 may have a predetermined, fixed, or adjustable length,wherein the length of hollow shaft 55 may vary based on the length ofcontainer 10. To facilitate an adjustable length, hollow shaft 55 mayinclude an inner and outer shaft. If coupled to a handle 50, the handlemay have a button configured to adjust and lock the length of hollowshaft 55 within container 10. Responsive to the button being pressed,the length of hollow shaft 55 may be adjusted. Responsive to the buttonno longer being pressed, the length of hollow shaft 55 may be locked inplace.

In other embodiments, outlet 55 b and inlet 101 may be configured foralternative lock, twist and or release mechanisms. Alternative twist andlock mechanisms may be utilized to open and/or close inlet ports and/oroutlet ports, such as first inlet port 55 a, outlet port 55, and/orsecond inlet port 101. For example, in a first position handle 50 and/oroutlet 55 b may be in an open position configured to allow air, fluid,and/or other substances to move from first inlet port 55 a to content100. In a second position, handle 50 and/or outlet 55 b may be in aclosed position configured to prevent air, fluid, and/or othersubstances from moving from first inlet port 55 a to content 100.

FIGS. 9A-9D show an embodiment of System 1000 including an encasement,shroud, or bag 70 with a first end 71 and a second rim end 73. Bag 70may serve as a delivery shroud configured to protect content 100 andfacilitate to movement of content 100 while being inflated and releasedfrom the container 10. Additionally, a bag 70 may prevent content 100from sticking to inner surface 11 or breaking, tearing, ripping uponmovement through container 10. Simply by pushing shaft 55, a medicalpractitioner may cause the encasement to unfold and deliver content 100into a patient as described by the embodiments below.

FIGS. 9A and 9B show an embodiment wherein the second rim end 73 isaffixed or adhesed to, on, and/or around second end 30 of container 10.Rim end 73 may be substantially the same diameter as the second end tofacilitate coupling. The figures also illustrate the first end 71 of bag70 affixed or adhesed to on or around outlet 55 b, or on the rim surfaceof outlet 55 b in contact with inlet 101 a. First end 71 may include ahole 74 configured to facilitate passage of passage of inlets andoutlets, for example, outlet 55 b and/or inlet 101 a.

FIG. 9A and FIG. 9B show that first end 71 of bag 70 may be configuredto move from a first position to a second position, respectively, whilethe rim end 73 remains fixed to the second end. In the first position,the first end 71 and rim end 73 are extended from outlet 55 b to thesecond end 30 of container 10, respectively, to encase content 100. Asoutlet 55 b pushes the first end 71 past the second end 30, the bagwalls unfurl or reverse so the interior walls 70 a of the bag at thefirst position is partially exposed to the exterior, and the exteriorwalls 70 b of the bag at the first position is partially reversed intothe interior of the bag. When the bag is 70 fully extended and reversed,as shown in FIG. 9B, outlet 55 b is pressed against first end 71. Inthis position, the bag's walls are unfurled or reversed so the interiorwalls 70 a of the bag at the first position are exposed to the exterior,and the exterior walls 70 b of the bag at the first position arereversed into the interior of the bag. In this position, the first end72 is distal to rim end 73, which has remained in a fixed position.

In other embodiments, first end 71 is positioned adjacent to, on oraround the proximal portion of content 100. However, in thisconfiguration, the bag is released into the patient along with thecontents 100. The first end 71 or bag hole 74 may also be affixed oradhesed to outlet 55 b, and/or inlet 101 a.

FIGS. 9C-9D show an alternative embodiment of bag 70 wherein the rim end73 or wall of the bag is affixed, attached or adhesed to any point alongthe inner surface 11 of container, between the first end 20 and secondend 30. First end 71 may be positioned adjacent to, on or around outlet55 b or between outlet 55 b and inlet 101 a. First end 71 may include ahole 74 configured to facilitate passage of passage of inlets andoutlets, for example, outlet 55 b and/or inlet 101 a.

In the first position illustrated in FIG. 9C, the first end 71 isrecessed into the bag 70, so that the walls of the bag are folded andcloser to the second end of the container than first end 71 or rim end73. In this orientation, the bag walls form a double layer to encase thecontents, which are positioned into the recess of outer wall 70 b.Outlet 55 b may travel from the first end 20 to the second end 30 of thecontainer 10, incrementally pushing the first end 71 away from the firstend 20 of the container towards the second end 30 of the container.

FIG. 9D shows a second configuration wherein outlet 55 b has pushed thefirst end 71 past the second end 30, the recess is eliminated, and bag70 is fully extended. In this position, the inlet end 72 is distal tothe rim end 73, which has remained in a fixed position.

In other embodiments, first end 71 is affixed, adhesed, attached orpositioned adjacent to, on or around the proximal portion of content100. However, in this configuration, the bag may be released into thepatient along with the contents 100.

The embodiments illustrated have an additional benefit of preventing theoutlet 55 b from being delivered outside of system 1000 along withcontent 100. Specifically, when content 100 is released, the bag 70enshrouds outlet 55 b and prevents it from falling out of the deliverysystem, despite being positioned distal to the second end. This bagembodiment may obviate the need for a clip 59 of certain ridges orprotrusions on the exterior surface 55 c of outlet 55 b.

It should be appreciated that bag 70 may be comprised of sufficientstrength, stiffness, rigidity, or durability. Bag 70 may be comprised ofplastic, polyurethane, nano-fibers, non-stick materials, or otherbiocompatible materials, and bag 70 may be configured to be scrunched,folded, or compacted.

FIGS. 10A-10D show an embodiment of System 1000 including one or moreprongs 200 including a first prong end 220 and a second prong end 230.Prongs 200 may serve as a delivery shroud configured to protect content100 and facilitate to movement of content 100 while being inflated andreleased from the container 10. Additionally, prongs 200 may preventcontent 100 from sticking to inner surface 11 or breaking, tearing,ripping upon movement through container 10. Simply by pushing shaft 55,a medical practitioner may cause the prongs 200 to unfold and delivercontent 100 into a patient as described by the embodiments below.Additionally, the prongs 200 may be released with content 100, andserves to create a perimeter around content 100, for example to create a“Y”, “V”, or “U” shape or other desired shape or configuration.

FIG. 10A shows an embodiment wherein prongs 200 are be positionedbetween the inner surface 11 and content 100 in a first position, andthe first end 220 is coupled to content inlet 101. FIGS. 10B and 10Cshows a second position wherein inlet 101 is positioned at the secondend, and the prongs are released outside of container 10. FIG. 10D showsa fourth configuration wherein the prongs are released with contentinlet 101 and content 100, and serves to create a perimeter aroundcontent 100 to create a “Y”, “V”, or “U” shape.

FIGS. 11A-11B show an embodiment where prongs are convex, as opposed toconcave as shown in FIGS. 10A-10D. Additionally, prongs 200 may bestraight without curvature, rigid, malleable, or flexible. Some portionsof the prong may be curved while other portions straight, as shown inFIGS. 11A-11B. Some portions may be flexible with other portions rigid.For example, prong end 230 may be soft and malleable, whereas the armportion of the prong is rigid. Additionally, prongs 200 may have arectangular, trapezoidal, oval, circular, any polygonal or mixed shape.Prongs 200 may be rectangular with rounded ends, collinear tubes, or acompliant cylinder that distorts or conforms.

The total perimeter of one or more prongs may be attached, affixed orcoupled to the perimeter of content 100. Alternatively, portions ofprong(s) 200 may be attached, affixed or coupled to the perimeter ofcontent 100. The distance between the first prong end 220 and secondprong end 230 may be greater, equal, or lesser than the length ofcontent 100, inlet 101, outlet 55 b, container 10 or any components ofsystem 1000.

FIGS. 11C-11D show an embodiment where the first prong end 220 iscoupled to outlet 55 b. First prong end 220 may be coupled or affixed tooutlet 55 b, container 10 or another portion of the system 1000. In thisconfiguration, prongs 200 may be limited or prevented from beingreleased with content 100 and achieving a desire configuration ofcontent 100 but may serve additional manipulation functions of the outertube in a surgical context.

When prong 200 is coupled to content 100, and content 100 include one ormore balloons connected to an elongated lumen, tube or member(hereinafter “elongated member 110”), the prongs 200 may be coupled to aportion of content 100 or elongated member 104 (as shown in FIGS. 11A &11B) to prevent an obstruction of vessels or a tourniquet effect onvital organs of the patient, such as the mesentery, bowel, or othersurrounding organs. For example, if the elongated member 104 is toothin, it may cut into vessels on a vital organ when a force, such as agravitation force, is exerted upon the content 100 (especially ifinflated with fluid). Or the elongated member 104 may obstruct the flowof blood or create a tourniquet. Examples of important vessels includethe aorta and common iliacs. A sufficiently thick elongated member 104may prevent blanching of the vital tissue and tissue of nearby organs,such as mesenteric, bowel, or other human tissue.

As shown in FIGS. 11A-11B, prongs 200 may be coupled to content 100 toprovide additional thickness to content 100 or elongated member 104 toprevent blanching or a tourniquet on delicate tissue or vital vessels.Content 100 may include one or more elongated members 104 coupled to onemore balloons 105. Therefore, prongs 200 may be coupled to one or moreinflatable balloons 105, or alternatively to an elongated member 104 toprovide additional thickness to balloons 105 or elongated member 104. Insome embodiments, the thickness achieved by the prongs may be 0-2 mm,2-4 mm, 4-6 mm, 6-8 mm, 8-10 mm, 10-12 mm, 12-14 mm, 14-16 mm, or 16mm-18 mm.

System 1000 may also facilitate inflation and delivery of the organretractor devices, as described in the '960 application or other balloonbased devices wherein the fluid amount desired to be injected is greaterthan 50 ml, for example between 100-200 ml, 200-300 ml, 300-400 ml,400-500 ml, 500 ml-600 ml or even greater than 500 ml. Such balloonbased devices may include one or more expandable balloon or portion,such as catheters.

Parts of the system 1000 and any content 100 may be constructed from avariety of materials, including but not limited to biocompatiblematerials, plastic, metal, cloth, textiles, synthetic fibers, nylon,rubber, Silicone (Polydimethylsiloxane), Polyurethane (e.g., AliphaticAromatic), Polycarbonate Urethane, Polyvinyl Chloride (PVC),Polyethylene Mesh or Film (e.g., LLDPE, LDPE, HDPE), Polypropylene Meshor Film, Nylon, Pebax, Polycarbonate, or other materials with otherappropriate or similar properties.

Parts of system 1000 and content 100 may have various coatings tofacilitate insertion, retrieval and placement of the device into apatient. This include lubricous time release coatings, surfacemodifications for lubricity, hydrophilic lubricous coatings

When content 100 is inflated with a fluid, the fluid may also be carbondioxide or another gas with similar properties through surgicalinflation techniques. Or it may be a magnetic fluid capable of fillingall inflating members (such as the anchor(s) 12 or elongated member 14).Such a magnetic fluid could interact with magnets or electromagnetsplaced internally in or externally on the patient.

The fluid within content 100 may be a biocompatible fluid that meetsregulatory requirements. For example, it may be water or physiologicsaline, dextran, malithol or other more dense fluids than saline.Biocompatible fluids guard against adverse effects during a leak. Thefluid may also be varied to have different flow rates and densities tocontrol balloon weight, rate, position and distribution of inflation.Also, fluid variations may be employed to change or adapt the amount ofweigh.

Content 100 may have a relatively distensible wall so as to allowthickening and inflation by the injection of the fluid. For example, theelongated member 14 may be constructed similar to (but larger in scalethan) some angioplasty balloons or balloons used in Foley's catheter,Humi, or V-CARE instruments to stretch or unfold into desired shapesthat optimize weight and positioning.

When magnets are employed in the device, for example as anchor(s) 12,the magnet could be of various types, including but not limited toAlnico, NdFeB, Ferromagnetic Alloys or similar magnets with otherappropriate or similar properties.

The content inflation and delivery system and its various embodimentsmay be packed, sold or delivered as a kit with a surgical tool ordevice, including the organ retractor described in the '960application”), or other devices that require inflation by a fluid, suchas a catheter or other balloon based devices. In addition, one or moredevices may be sold in a system kit. For example, such a kit may includeone or more organ retractors. The device may come pre-assembled orseparately with the system. The kit may include other materialsincluding appropriate labeling, one or more sterile barriers (e.g., 1,2, or 3 or ore barriers), trays, bags, and a box. These other componentsmay be sterile.

System 1000 may be used with a variety of medical devices, including theorgan retractor described in U.S. Pat. App. Publication No.2012/13432960 entitled ORGAN RETRACTOR filed on Mar. 28, 2012 (“the '960application”). The '960 application shares a common inventor with thepresent application and discloses an organ retractor for facilitatingpositioning of a mesentery or organs connected to a mesentery within anabdominal cavity of a patient.

In a minimally invasive surgical context, the content delivery andinflation system may have the following dimensions and characteristics.The container (diameters 17 a and 17 b) may be 2 to 20 mm wide. Thecontainer or distance between the first end 20 and second end 30 may beup to 50 cm long, depending on the size of the inflatable content,whether it is used in a laparoscopic or robotic context, and theintended location (e.g., abdomen with a larger depth or hand with asmall depth). The length of the shaft may be up to 60 cm long. Thediameter of the shaft may be up to 20 mm wide. An individual prong maybe up to 40 cm long, depending on the context. These dimensions may belarger in an ordinary surgical context, or even in a minimally invasivecontext. In a laparoscopic embodiment, the length of the container is20-40 cm, the length of the shaft is 25 cm to 45 mm long, the diameterof the container is 5-10 mm, and the diameter of the shaft is 4-8 mm,and the length of the prong is 5-15 cm.

System 1000 may also facilitate inflation and delivery of the organretractor devices, as described in the '960 application or other balloonbased devices wherein the fluid amount desired to be injected is greaterthan 50 ml, for example between 100-200 ml, 200-300 ml, 300-400 ml,400-500, ml or even greater than 500 ml. Such balloon based devices mayinclude one or more expandable balloon or portion, such as catheters.
